PORTABLE SCREEN-BIN.

SPECIFICATION forming part of Letters Patent No. 770,353, dated September 20, 1904.

Application tiled August 15, 1903.

To L7/Z whom t may concern: Y

Be it known that I, DAVID BRADFORD COOK, of Frankfort, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Portable Screen- Bins; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form part of this specification.

The object of this invention is to provide a portable and partially-collapsible screen-bin with screen particularly adapted for use with stone-crushing outfits. A screen and screenbin is a necessary part of a well-equipped stone-crushing outfit, and in the modern practice of using such outfits in making roads and otherwise and frequently transporting them from place to place the transportation of a suitable screen or screen-bin is a matter of considerable moment. Screen-bins as heretofore provided have been unwieldy and practically non-transportable without taking them entirely apart, which is decidedly an objectionable feature.

In the drawings, Figure 1 shows a perspective view of a screen-bin with screen of my improved construction, with the screen elevated in operative position and the extension sides opened or extended. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a perspective view with the upper portion of the walls of the bin collapsed and the screen lowered nearly into position for transportation. Fig. 4 is a cross-section of a bin embodying the features of my improvement. Fig. 5 is an end view of the same. In Figs. 4 and 5 the screen is shown in its elevated or working position.

Referring to the drawings, A indicates the framework of the bin, which at the upper portion is provided with end walls 2 2, applied to the inner side of the framework, and side walls 3 3, applied to the outer side of the framework. These end and side walls form an inclosed receptacle for holding crushed Serial No. 169,574. (No model.)

stone or other materials. The bottom 4 of the bin is slanting or inclined, and preferably of a hip-roof form, so as to slant from the center downwardly and outwardly in both directions, and is supported on rafter-like pieces 5, constituting a portion of the frame. The lower portion of the frame is provided with beams 6, which when the bin is located for use are 'adapted to be blocked up or underpinned. The frame is also mounted on carrying-wheels 7 7 and 8 8, constituting a truck.

The upper end wall portions 2 of the bin are hinged at a and are adapted to fold inwardly. The upper side wall portions 3 are also hinged to the bin-frame at I) and are adapted to fold inwardly. Within the bin there may be provided cross-partitions 10 11, which are hinged at their lower portions and adapted to fold, as indicated in dotted lines in Fig. 2, or the same may be made removable. In connection with the bin there is provided a screen-frame B, consisting more particularly of an upright frame 12 at each end of the bin and connecting-bars 13. The frames 12 are arranged to slide vertically in ways or guides 14, provided in the framework on the end of thel bin.

A rotary screen C is preferably employed and is properly supported in the screen-frame B. The said screen C preferably comprises sections of diiferent meshes, so as to divide the material into different grades to be received in the compartments of the bin afforded by the partitions 10 11. The screen C is of lesser length than the bin, so that the coarse material issuing from the end of the screen may be delivered into a compartment of the bin and also so as to permit said screen to be lowered into the bin for transportation.

Extending lengthwise of the bin under the apex of the bottom there is provided a shaft 15, which is mounted in suitable bearings on the frame at each end. This shaft is a reelshaft and has a chain 16 or other suitable connection connecting the reelshaft with the lower end o`f the frame 12. On one end of the reel-shaft there is provided a ratchetwheel 15, with pawl for securing the reelshaft in any desired position, and in connection therewith there is also provided a pawl and lever 17 or other suitable means for operating the shaft. r

After folding in the end walls 2 and the side wall 5a of the bin and after the cross-partitions l() and l1 have been folded or removed the pawl securing the shaft l5 may be released, when the screen-frame will settle into its lower position, with the screen in the upper portion of the bin proper. In this position the bin and screen are of a suitable size or height for transportation along ordinary roads and across ordinary bridges, and the device is not top-heavy. When the device is to be used, the screen, with the screen-frame, is elevated into working position and the extension-walls of the bin are turned up to form an extension of the bin proper, and the crosspartitions are suitably placed.

From the foregoing it will be apparent that the invention provides a bin or inclosed receptacle mounted on wheels for convenient transportation and which bin or receptacle is provided with a vertically-adjustable frame carrying a screen which may be raised when desired for use or lowered into convenient position for transportation. The bin or receptacle is made extensible by being provided with the folding sides and ends with which it is furnished at its top, so that it may have a large holding capacity when -the screen is in its elevated position. Moreover, the inclined bottom of the bin provides a convenient means for discharging the contents thereof through side doors into suitable chutes, with which the bin is provided, while the internal partitions with which the bin is preferably furnished afford a series of compartments intoy which screened materials of various grades. may be received. y

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with an inclosed receptacle or bin, of a vertically-movable frame, a screen mounted on said frame, and means whereby the screen-frame may be raised or lowered to elevate the screen into working position or to lower it into position for transportation, said bin being provided at its top with collapsible ends and sides to form an upper extension for said bin when the screen is raised.

2. The combination with an inclosed receptacle or bin, of a vertically-movable frame, a rotary screen mounted on said frame and of lesser length than the said bin, and means whereby the screen-frame may be raised or lowered to elevate the screen into working position or to lower it into position for transportation, said bin being provided at its top with collapsible ends and sides to form an upper extension for said bin when the screen is raised. l

3. The combination with an inclosed receptacle or bin, of a vertically-movable frame, a screen mounted on said frame, and means whereby the screen-frame may be raised or lowered to elevate the screen into working position or to lower it into position for transportation, said bin being provided at its top with collapsible ends and sides, to form an upper extension of said bin when the screen is raised, and with an inclined bottom for the convenient discharge of material held therein.

4. The combination with an inclosed receptacle or bin, of a vertically-movable frame, a rotary screen mounted on said frame and of lesser length than the said bin, and means whereby the screen-frame may be raised or lowered to elevate the screen into working position or to lower it into position for transportation, said bin being provided at its top with collapsible ends and sides to form an upper extension for said bin when the screen is raised, and said bin having an inclined bottom for the con venientdischarge of material therefrom.

5. The combination with an inclosed receptacle or bin having aseries of compartments, of a vertically-movable frame supported by said bin, a rotary screen divided into sections of different meshes, said screen being mounted on said frame and of lesser length than the said bin, and means whereby the screen-frame may be raised or lowered to elevate the screen into working position or to lower it into position for transportation, said bin being pro.-

. vided with an inclined bottom for the convenient discharge of material held therein, and said bin having collapsible ends and sides at its top to form an upper extension of said bin when said screen is raised. v

In witness whereof I have affixed my signature, in presence of two witnesses, this 24th day of July, 1903.

DAVID B. COOK.
